HSN Code Details
Acids of arsenic are specialty chemicals used primarily in the semiconductor and electronics manufacturing sector to etch and clean silicon wafers. These compounds are produced in highly controlled laboratory environments to meet stringent purity standards.
When shipping arsenic acids, consignments must be sealed in double‑lined, chemically resistant containers and accompanied by a hazardous material manifest. Exporters should also provide a Certificate of Analysis and ensure compliance with the International Atomic Energy Agency (IAEA) regulations.
